SEPARABLE BUTTON.

Application filed July 8, 1925, Serial My said invention is animprovement on the button disclosed inmy United States Letters PatentNo. 14,342, reissued August '4', 1917, and aims to provide aconstruction which may be more easily and economically manufactured,which will enable the button. parts to be separated by a reduced lengthof movement in the locking key, and in which the part receiving thethrust of the key will be of ample strength.

Vfith these several objects in view, the invention includes the novelfeatures of construction and arrangement and combination of partshereinafter described and particularly defined by the appended claims.

In order that the invention may be more readily understood, reference ismade to the accompanying drawings, in which Figure 1 is a transversevertical section through a complete assembled button.

Fig. 2 is a sectional view of the lower half of the shell or femalemember.

Fig. 3 is a plan view of the same, and

Fig. a is a plan view of the key blank before it is bent into the shapeshown in Fig. 1.

In this drawing the female member is shown as comprising a shell formedby a top member 5 having two slots 6 cut through it, leaving a cross bar7 which is bent into the arched form shown in Fig. 1, and through whichthetwo legs 9 of the key member are inserted, as in my aforesaid patent,the cap member being .secured to the main shell member 16 by having itsedges spun around the edges of the latter. The shell or lower member 16is provided with a tapered lower portion of substantially truncatedconical form and the lower edge is curled upon itself to form astrengthening or reinforcing head, as indicated at 16*.

The male member of the button is indicated at 18 and it has a shankportion adapted to penetrate the open lower end of the female member,which shank is provided with an annular reduced portion 18 which, whenthe upper end of the shank is juxtaposed to the bridge piece, coincideswith the beaded portion 16 of the shell. The legs of the cap piece ofFig. 4, after it has been bent into the shape shown in Fig. 1 andinserted through the slots, are adapted to engage with the shank justabove its point of minimum contraction, and by being wedged between theshank and the contract- No. 42,246.

member may be released by a much less degree of movement.

The key 18 operated for releasing the male member in the manner asdisclosed in my aforesaid patent, by a cap member 10 which 7 hasover-turned side edges which engage the head of the key piece. In myaforesaid patentthe head of the key piece was provided with sideportions curved to correspond to the curvature of the edge of the cappiece and considerable difficulty was experienced in effecting a properand permanent junction, due to the tendency of the corners from underthe turned over edge of the cap. I have found that this objection can beavoided by making the cap engaging portion 9 of the key piece relativelynarrow, which gives an amply firm connection and enables the key pieceto be formed up into the proper shape more readily.

Having thus described my invention, What I claim is 1. In a separablebutton, a female or head member having a sheet metal body provided withatapered portion having an outwardly overturned lower edge forming anexternal annular head, a male member having a stud to enter the openingdefined by said annular bead, saidst-ud having an annular rebate,

' or ends of said curved portions to pull out and a key piece'havinglegs lying between I the lower end of the said tapered portion and thereduced portion of the stud, with means for operating the key piece.

2. A separable button according to claim 1, in which a cap having aninwardly turned flange is provided for operating the key piece, and thekey piece has a head comprising laterally projecting wings havingconverging side edges and relatively narrow rounded edges at the terminiof the converging edges for engaging the flange of the cap.

In testimony whereof I affix my signature JOHN V. PILOHER.
